Butterfly fish and other "picky" or delicate feeding marine tropical. In the their natural coral reef environment, Marine Butterfly fish, Angels, Tangs and many others feed by picking throughout the day on surfaces of coral heads and live rocks. The Grid Feeding Clip helps to duplicate this natural feeding behavior by holding food intact and prolonging the feeding process so that fish are not forced to eat their entire day's food in a five-minute rush. It also allows your fish to feed in this natural picking manner rather than eating food floating in the water column.

Fish with protruding snouts can actually pick pieces of food right through the openings of the plastic grid until the entire portion of food is devoured. This process prolongs the feeding period up to one hour and allows for much greater enjoyment for the hobbyist who wishes to observe this more natural feeding behavior.
